Sound wave travels from one part in to another part in air due to change in density of molecules from one point to another point
No sound can travel through space. Sound travels by vibrating adjacent molecules. The sound wave travels along these molecules until it dissipates with distance. In the vacuum of space, there are no molecules (this is not considering celestial bodies like planets or meteors because they are not a part of the vacuum), so sound cannot travel.
Sound waves that are compressed are made of (air) molecules that are more densely concentrated - that is (ie) more molecules are packed into the space of the compressed wave than there are in the (same) space of the surrounding expanded waves.
i know density is the molecules in the heat when the molecules are heated they spread apart and rise then over time they cool down and sink when they are cold they come together like when you're cold you want to bundle up to warm up and when you're hot you don't want anyone near because you want to cool off i don't know about volume but i'm guessing it's how many molecules are in air if there are a lot of molecules in heated air it rises more because the molecules bounce off of each other when there are many molecules in cold air they heat faster because there are more molecules but I don't know I hope the density part helps

the molecules in the air closer to us makes the sound clear.where as the distant sound is not as clear as the molecules will be far a part.
it is called the compression
Some other part of the crust must be "disappearing" (subduction).

Compression is the part of a longitudinal wave where the particles of the medium are crowded together. Rarefaction is the part where the particles are spread apart.
